My 13 mth old x-breed staffy has started to vomit, for apparently no obvious reason. He is still charging round like an absolute nutter, is not off his food/water and his bladder/bowel movements are perfectly normal.
When he eats his food, which is the same he has always had, over the past 4 days he has brought it back up again, but not always. It is not blood stained, it is just mixed with a lot of mucus. After he has finished reaching he will clear up his vomit and then goes about his normal energetic behaviour. This vomiting is not only accuring following feeding, it is sometimes happening at other times of the day, then he just brings up very sticky, bubble blowing mucus, sometimes he clears this from his mouth, other times he swallows it back down.
I am finding this very puzzling, as like I say, apart from the being sick he is behaving completly the same as normal.
We have another dog and when my staffy x has brought up his food or been sick, the other dog is very interested in what has come out, but my staffy x is being very protective of his vomit. Is what my staffy x is doing just a way of excerting his authority or is there some other underlinning health problem. Not meaning to repeat myself, but all his other functions are normal, his not tender anywhere and he is still as lairy as ever. All feedback is gratefully received thank you.

Hi I am no expert on vomit but it could be because he is 'bolting' his food down, my Labs eat like aligators and the food comes back up if they wolf it down too quickly. IF his vomitting follows excessive whizzing around I would suggest this is why and as it is not even partially digested it is still his valued possession and no way is he going to let someone else have his dinner:)

My lab does this often because he has a hiatus hernis. This is very rare . A more common reason would be that he has eaten something which is sitting in his stomach. I would seek your vets advice just in case.

Thanks for your replies. Yes my staffy x is a bit of a gannet guzzler and does tend to bolt his food at an alarming rate. The something sitting in his stomach is something to think about. If he had eaten something he shouldnt have would he not pass it out or be constipated/or loose? I will try to get him to slow down when eating his food and not to be over energetic straight after, and if this still doesnt appear to help then I will see the vet for advice and suggest that he may have eaten something and get that checked out.
